Abstract
Abstract Wireless ad-hoc networks with different topologies proved to be a feasible solution for low-cost deployment of computer networks. It provides quick and easy networking in circumstances that require temporary network services or when cabling is difficult to be installed. In this paper, an analytical model of a wireless ad-hoc network is presented, in addition, a new model for wireless ad-hoc network with a sub-layer MAC is designed using Simevents tools. It is also taken into account the effect of the contention process and losses on the sub-layer MAC, then OPNET software is used to validate this model. Finally, the results of a practical single-hop wireless ad-hoc network using six computers are compared with the results of the proposed models. It is obvious that there is an excellent agreement between the throughput performances of the different models. Key words: Wireless, Ad-Hoc, MAC, Simevents.
